Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

steel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

Nongravitational Forces in Planetary Systems

The Planetary Science Journal
Nongravitational forces play surprising and, sometimes, centrally important roles in shaping the motions and properties of small planetary bodies. In the solar system, the morphologies of comets, the delivery of meteorites, and the shapes and dynamics of

Dna damage in myocardial cells of rats with experimental alcoholic cardiomyopathy: modifyng effects of fabomotizole and trimetazidene

Фармакокинетика и Фармакодинамика, 2018
Resume. Relevance. Alcoholic cardiomyopathy (ACM) is a specific heart muscle disease found in individuals with a history of long-term heavy alcohol consumption. Their underlying mechanisms are poorly known, leading to a lack of effective therapy. Related

A Thermodynamic‐Kinetic Model for Basic Oxygen Furnace Tapping: Improved Prediction of Phosphorus and Steel‐Slag Evolution

steel research international, EarlyView.
This study develops a thermodynamic–kinetic model for basic oxygen furnace tapping and validates its accuracy under near‐equilibrium and far‐from‐equilibrium initial conditions. Comparison with a reference model demonstrates its broader applicability. The model further reveals the evolution of key steel and slag components, providing new transparency ...

The effect of the Solar motion on the flux of long-period comets

, 2010
The long-term dynamics of Oort cloud comets are studied under the influence of both the radial and the vertical components of the Galactic tidal field.

First Assessment of Genetic Damage in the Speckled Cockroach (Nauphoeta cinerea) After Consumption of Lettuce (Lactuca sativa) Cultivated and Commercialized in Northeastern, Brazil

Environmental Toxicology, EarlyView.
ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,

Brightness Behavior of Distant Oort Cloud Comets

The Planetary Science Journal
Dynamically new comets provide important insights into the conditions of the presolar nebula and its evolution, as they are believed to have experienced minimal solar heating before their discovery.

The NEOWISE-Discovered Comet Population and the CO+CO_2 production rates [PDF]

, 2015
The 163 comets observed during the WISE/NEOWISE prime mission represent the largest infrared survey to date of comets, providing constraints on dust, nucleus size, and CO + CO_2 production.
